That sounds a lot like my symptoms. Hopefully the month of rest did me some good. I'm DLing tomorrow or Wednesday. Even though I intend on going light it will be my first real test.
good luck. i used to get an aura feeling that went from my balls up to my diaphram and down to my knees. that was always followed by severe discomfort in my left testicle for weeks at a time. take it slow. once i began to feel that aura i knew i fucked up and strained it again.
